Question

0.3*(0.6х-8.4)=-9*(0.8х-3)

Answer 1

0.18х-2.52=-7.2х+27
0.18х+7.2х=27+2.52
7.38х=29.52
х=29.52:7.38
х=4
Ответ:4

Answer 2

To solve the equation 0.3*(0.6x-8.4) = -9*(0.8x-3), follow these steps:

Step 1: Distribute the values inside the parentheses. Step 2: Simplify both sides of the equation. Step 3: Isolate the variable 'x' on one side of the equation. Step 4: Solve for 'x'.

Let's proceed with the steps:

Step 1: Distribute the values inside the parentheses: 0.3 * 0.6x - 0.3 * 8.4 = -9 * 0.8x + 9 * 3

Step 2: Simplify both sides of the equation: 0.18x - 2.52 = -7.2x + 27

Step 3: Isolate the variable 'x' on one side of the equation: Add 7.2x to both sides and add 2.52 to both sides:

0.18x + 7.2x = 27 + 2.52 7.38x = 29.52

Step 4: Solve for 'x': Divide both sides by 7.38:

x = 29.52 / 7.38 x = 4

So, the solution to the equation is x = 4.
